Product Details

ROHM's sound processors deliver high-fidelity audio, are easy to use, integrate a two-band equalizer, and are compatible with power supply voltages between 4.75V and 9.5V due to low current consumption operation, making them ideally suited for use in portable stereo systems.

Low noise (5μVrms(TYP.)) and low distortion(0.002% (TYP.)).
Built-in simple surround. Furthermore, it can constitute good surround of sound image normal position with an external part.
It can constitute a bass boost or output gain with an external part.
When the volume setting exchanging, it can use a volume terminal as a microphone input terminal because there is not an impedance change of a volume terminal.
Bi-CMOS process is suitable for the design of low current and low energy. And it provides more quality for small scale regulator and heat in a set.
The package of this IC is SSOP-B28. It gathers a sound input terminals, sound output terminals respectively and it arranges them, to be arranging facilitates the laying-out of PCB pattern and reduces PCB area to one-way in the flow of the signal.
